voAa-oooa LOCK.

SPECIFICATION formingpart of Letters Patent No. 279,732, dated June 19, 1883.

Application filed February .17, 18:33. (No model.)

To all whom; it may concern.-

Be it known that I, J OSEPH HYDE FISHER, of Deerfield, in the county of Lake and State of Illinois, have invented new and useful Improvements in Car-Door Locks, of which the following is a specification, reference being had to the accompanying drawings, illustrating the improvement, in which Figure I is a broken face view of the inside of a ear-door and door-post with my improved lock attached to the door and in position to lock the same; Fig. II, a horizontal section of the devices shown at Fig. I, and in addition thereto the lower door-guide and a portion of the side of the car; Fig. III, an elevation of the lock detached from the door and the locklever turned back, as when the door is unlocked and free to slide open. 1

The present invention relates to locking car-doors atthe insides of freight-cars.

The nature of the invention, in brief, consists in what I term a lock -lever so pivoted to a metal frame that where it'is swung in one direction one end will project above the frame and butt against the door-post, and thus hold the door fast, and so that where it is turned in the opposite direction the pro je'cting end will fall into a recess and lie below or even with the inner surface of the door, and not interfere with the opening thereof. One form of so holding the "lock-leve'r sufficiently rigid in the aforementioned positions consists of a spring whose ends are supported by the ends of the frame, so as to bear against the inner end of the lock-lever, the pivots of the lever acting as fulcrums, as the whole is hereinafter fully described and shown.

A represents a broken elevation of the inside of the door of a freight-car, and B a broken elevation of the door-post, as shown at Fig. I, the same parts being shown at Fig. II in a horizontal section. The door is constructed to slide to the right when being opened, and to pass no farther to the left than to' bring the end S against the door-post B, as shown at Figs. I and II.

0 C represent the face-plate of the lock frame, and L L the ends, which connect with the inwardly-projecting ribs Y, oastsolid to the faceplate C O.

. The'lock-lever consists of bars IV V and an enlarged head part, S F, the latter, as a matter of convenience, being beveled at E to save iron. A hole, 00, is made through the head, that a seal or other device may be applied to show whether the lock has been tampered with. On the sides of the bars V W, a sufficient distance from the inner end of the lock-lever to form a fulcrum with reference to the spring H, are formed pivots, {shown by dotted lines K K,) which have bearings in the sides Y of the frame. 7

On the ends L L of the frame are formed spring-seats a. a b, to support the spring H and prevent it from getting out of place by the action of the end of the lock-lever. I use this form of spring in preference to other forms of springs to hold the lock-lever in position, it being much simpler and cheaper. Other springs, however, may be substituted. Antifriction roller I is pivoted to the inner end of the lock-lever to insure the easier working of the parts; but it is not necessary for any other purpose. The device is operative without it. Between the head S F, the bars XV W, and the roller I is formed a slot, or. This is that the finger may be put through it to lift the Any other lock-lever and change its position. finger hold on the lock lever would be an equivalent therefor.

It is proper to state that the lock is adapted to locking other doors than those of cars.

The dotted lines 2, Fig. II, represent the position ofthe lock-lever, the same as at Fig. III, and the dotted lines y show the position of the lever when one-half turned, and P the position of the spring at that time. It 0 show how the door is recessed out to give space for the spring to work. '0, Fig. III, shows the screw-holes through which screws (1, Fig. I, are 'put to hold the face-plate of the frame to the door.

Having thus described my invention and the method of operating the same, I claimand desire to secure by Letters Patent 7 A car-door lock consisting of a"face-plate, O 0, formed with inwardly-projecting ribs Y Y, and end pieces, L L, the latter formed with spring-seats a a b, in combination with aspring, H, bearing on the seats, and a lock-lever con- IOO sisting of bars V \V and enlarged head S the moving door and be held in both positions F and pivots K K, the latter projecting out by the spring H, substantially as specified and from near the inner end of the lock-lever and shown. entering bearings in the ribs Y Y, to form a JOSEPH HYDE FISHER. 5 pivot-fulcrum for the lock-lever to be turned \Vitnesses:

on so as to bring the head S F against the car- G. L. CHAPIN, door, and to bring it back out of the way of J. S. HUEY.
